13 Claims.

, invention is not limited to this, application.

, One object of the invention is to provide a dumping or tipping mechanism of the type mentioned so arranged as to permit low pressures in a hydraulic actuating mechanism.

Another object is to provide in connection with .such a mechanism means whereby a relatively large degree of travel of the hydraulic or other actuating means takes place with each movement in the dumping direction. Thus with one mech anism for a five degree dump the hydraulic piston might move two inches, while with the mechanism of the present invention, for a similar amount of dump, the movement of the hydraulic mechanism is much greater and thus lower pressures are possible within the hydraulic system.

Other objects will appear from. time to time in the specification and claims.

The invention is illustrated more or less diagrammatically in the accompanying drawings,

wherein:

V Figure 1 is a side elevation with parts broken away, showing by invention applied to a dumping body; 7 V

Figure 2 is a horizontal sectional view taken on an enlarged scale .at line 2 2 of Figure lj, with parts omitted;

Figure 3 is a transverse vertical sectional detail taken generally at line 33 of Figure 2.

Figure 4 is a modification of the lever mechanism of Fig. 3.

Like parts are designated by like characters throughout the specification and drawings.

I, I are side frame members and may for example be the side frame or chassis members of a vehicle frame. They are joined by suitable cross members, one of which is shown as at 2. The particular details of the frame construction form no essential part of the present invention and are, therefore, not illustrated in detail. There will ordinarily be some frame upon which the dumping mechanism and the dumping body itself will be mounted.

A sub-frame is preferably provided for the dumping body. This may comprise side or longitudinal members 3; 3, of any desired shape and arrangement, and upon these is mounted a body 4. The body is of such size and shape as to contain the desired load. Depending downwardly from the frame members 3, preferably adjacent their rear ends are bracket members 5, which may carry bearing portions 6, trunnioned upon a transverse member lwhich in-the particular form here shown is a rod secured at its ends-to the vehicle frame members I. The dumping body 5 may have a tail gate 8 or any other closure or discharge member desired.

In the particular form here shown the power for the dumping or moving operation is furnished by hydraulic means. This hydraulic means or as- .10

sembly includes, among other features, a cylinder 9, pivoted or otherwise mounted for tilting move-' ment as at It) and supported in or from the frame I. A piston of suitable design is mounted within the cylinder to reciprocate. .Ii extends outwardly from the cylinder and is provided with an attachment member I2 which engages and preferably surrounds a transverse member I3. In the particular form here shown this member is a rodbut might have any other desired shape. 7

V Journaled on a transverse rod I4, which is mounted from or upon the side frame members I,

are a pair of links. As shown each pair comprises two parts I5, I5, which may be secured to a l 5 spacer I6, which are perforated to fit aboutthe rod I4 and are held in proper spaced relation upon the rod byspacers l1, IT. The members I5 are as shown particularly in Figure 3 bowed, bent or cut away so that in the full loweredposition of. Fig- 30 ure 1 they may extend over and remain out of contact with the transverse frame member 2 and any other mechanism or parts of the assembly. Between each pair of members I5, adjacent their free ends, is pivoted upon studsI8 an auxil- 35 iary lever member. I9. As shown generally in Figures 1 and 2, and more particularly in Figure 3, this auxiliary lever member is irregularly shaped and adjacent its upper margin receives. the transverse rod or; member I3 which is secured through the part I2 to the'piston rod II. Pushing movement of the piston rod is thus. effective upon the auxiliary levers I9. At its free end each lever I9 is provided with a roller contacting surface 20 which contacts rollers ZIsupported for rotation upon a transverse rod or frame member 22. The upper edge of each of the members I5 may be notched or provided with a depression 23. Pivoted to the lower or free end of each of the members I5, upon or concentric with the studs I8,

are links 24, which links are at their upper endspivoted to the body frame3 as at 25.

The form vof Figure. 4 is generally similar to that of Figure 3, but illustrates a modification which, for some purposes, is useful.- The struc- 5 A piston rod 18 wise movement of theauxiliary lever I9 with respect to the main lever I5. When the boss and hook are engaged the transverse member I3 is held against the upper surface of the lever I or held seated within the depression 23, where such a depression is provided. For some installations the hook and boss are desirable, or they may be omitted.

It will be realized that whereas I have herewith shown and described a practical operative device, nevertheless many changes might be made in the size, shape, numberand disposition of the parts without departing materially from the spirit of my invention and I wish, therefore, that my showing be taken as in a sense diagrammatic.

.In particular the arrangement of bearings and transverse members might be almost infinitely varied. For example, the transverse members I, I 3, I4 and 22 might be rods or of any other shape. The trunnioning or supporting of the members I5 might be of any desired arrangement and the support for the rollers 2I might be otherwise than'as shown.

The use and operation of my invention are as follows The dumping receptacle, whether it be mounted on a vehicle'or not, is supported generally in the position shown in Figure 1, when it is to receive or contain a load. The power for dumping may come from the hydraulic cylinder as shown or from other means. If a hydraulic cylinder is used the pump may be mounted to pivot with the cylinder or "may be otherwise mounted. Whatever the exact power source, when the body is to be tipped the power is so controlled that the piston II or its equivalent moves to the right from the position shown in Figure l toward the positions shown in Figure 3, thus bearing upon the transverse member I3 and through it upon the upper corners or edges of the auxiliary levers I9 and tending to rotate them downwardly about their pivots on the studs I8. Since the faces 20 of the levers I9 are in contact with rollers 2I they cannot rotate downwardly and the exertion of force upon the levers I9 tilts them upwardly, the levers being fulcrumed at some point of their faces 20 upon some point of the rollers 2I. As the levers I9 tilt upwardly to this position they carry with them the free ends of the members I5 and correspondingly raise the body or tilt it through links 24 which are pivoted both to the body and to the members I5.

After a certain amount oftravel hasoccurred the transverse member I3 normally contacts the upper surfacesof the members I5. These may be notched as at 23 if desired. 7 The parts are so proportioned that the contact of the transverse member I3 with the upper surfaces of the members I5occurs at or approximately at the point when the faces'2l! of the levers I9 break contact with the rollers 2 I. iary effect of the. levers I9 is terminated and thereafter during the remainder of moving, or tilting movement, the member's I5 act merely When this occurs the auxilas levers rotating about their axes, that is to say, about the axes of the transverse member I4.

The position of the levers and associated parts 7 as shown in full lines in Figure 3 is that which they assume at or approximately at the completion of the auxiliary effect of the auxiliary lever I9, where it leaves or is about to leave contact with the rollers 2|. The dotted line position of the parts shown in Figure 3 is that which they assume at or approximately at the maximum movement for an assembly designed with the proportions shown. Obviously an assembly might be designed to have a greater or less maximum movement than that shown.

As the body and its. associated parts move from the full line position of Figure 3 toward the,

dotted line position, the auxiliary levers I9 have no further lever action and serve merely as links to connect the free'ends of the levers I5 to the transverse member I3 upon which the power source is acting. As the parts reach or approach their position of maximum movement the transverse member I3 may or may not lift slightly out of the notch 23. Whether or not this effect occurs depends upon the design of the parts and in particular upon the angular relationship between the parts and the hydraulic piston I I or its equivalent. The location of the pivot point for the cylinder 9 largely determines whether or not the transverse member I3 lifts out of the notch or out of contact with the upper surface .mechanism of Figure 4, the counter-clockwise movement of the auxiliary lever I9 with respect to I the main lever I5 is positively prevented, irrespec tive of the other features of design and irre-' spective of the angular relationship of the parts, or the angular disposition and movement of the hydraulic piston II.-
